Circular tube billet and heating to punch, three-roll skew rolling, rolling, or pressing - pipe - sizing (or reducing) - cooling - straightening to hydrostatic test or inspection - > tag, warehousing seamless steel tube is made from solid tube ingot or the perforation capillary, then through hot rolling and cold rolling or cold dial.The specification of seamless steel tube is indicated by the outer diameter * wall thickness mm.Seamless steel pipe is divided into hot rolling and cold rolling (dial) seamless steel tube.Hot rolled seamless steel tube, low, medium pressure boiler tube, high-pressure boiler tube, alloy steel tube, stainless steel tube, petroleum cracking pipe, geological steel tube and other steel pipe.Cold-rolled (dial) seamless steel tube in addition to general steel tube, low medium pressure boiler pipe, high pressure boiler tube, alloy steel, stainless steel pipe, oil cracking pipe, steel pipe, other include carbon thin wall steel tube, alloy thin wall steel pipes,

thin-walled stainless steel tube, steel tube.Generally greater than 32 mm hot rolled seamless steel tube diameter, wall thickness 2.5 200 mm, cold rolled seamless steel tube can be to 6 mm in diameter, wall thickness to 0.25 mm, to 5 mm thin wall pipe diameter thickness less than 0.25 mm, cold than hot rolled high dimensional accuracy.
